甲烷转化系统工艺参数的调控

Regulation of process parameters of methane conversion system

甲醇做为重要的化工基础产品之一,应用十分广泛。甲醇主要是由CO、CO_(2)、H_(2)反应合成。陕西延长中煤榆林能源化工有限公司采用油田气(主要成分是甲烷)与水蒸气按照一定比例混合,在一定温度、压力以及催化剂的作用下发生甲烷转化反应,生成CO、H_(2)、CO_(2)和水蒸气的混合物,实现这一重要反应的主要设备是转化炉,其设备在运行过程中的使用效率及可靠性对整个系统的影响很大。装置在运行期间针对操作上的优化主要是关于核心指标的控制,本文通过对水碳比、转化炉的温度、进入转化炉的流量、系统压力的精心调控来提高转化炉的效率,旨在节约成本,降低能耗。

As one of the important basic chemical products,methanol is widely used.Methanol is mainly synthesized by CO,CO_(2) and H_(2) reaction.In Shanxi Yanchang Coal Yulin Energy and Chemical Company,oilfield gas(mainly composed of methane)and steam are used to mix in a certain proportion,under a certain temperature and pressure and the action of catalyst,they undergo methane conversion reaction to generate a mixture of CO,H_(2),CO_(2) and steam.The main equipment to realize this important reaction is the reformer,of which the use efficiency and reliability during operation have a great impact on the whole system.During the operation,the optimization of operation is mainly about the control of core indicators.In this paper,through carefully regulation of the water and carbon ratio,the reformer temperature flow rate into the reformer and the system pressure,the conversion rate is improved,the costs are saved and energy consumption is reduced.
